Abstract Electrochemical impedance spectroscopy (EIS) measurements were performed on sensitized and solutioned 304 stainless steels respectively in the process of Electrochemical potentiodynamic reactivation (EPR) polarization in 0.5mol/L H2SO4+0.01mol/L KSCN solution.The variation rules of impedance resistance in process of EPR polarization were analyzed.It was found that the EIS spectra of the stainless steels during EPR polarization exhibited features of active dissolution,activation-passivation,passivation and reactivation.Before reactivation,the two kinds of stainless steels had the same EIS characteristics.In the reactivating region the passivated film dissolved partially and the impedance modulus of the sensitized stainless steel was one magnitude order smaller than that of the solution-treated stainless steel,indicating that intergranular corrosion had occurred on the surface of the sensitized stainless steel.In addition two capacitive loops appeared in the EIS of the sensitized stainless steel and it was quite interesting that the second arc at the low frequency range was actually a negative resistance capacitive loop.These results may provide essential basis for detecting intergranular corrosion susceptibility of stainless steel by electrochemical impedance spectroscopy.
